Fire chiefs in Essex have been accused of undermining relationships with union members, ahead of a second fire-fighters' strike.
The one-hour strike is scheduled for 4 o'clock this morning. But any firefighters taking part have been warned they'll be forced out of bed - and off the premises - depsite the unsociable hour.
The Fire Brigade says they'll be considered trespassers if they stay in the building.
Union officials say they're protesting against a reduction in front-line firefighter numbers but the fire service says it has made a number of concessions, including promising there will be no redundancies.
